Unfortunately, your guess is as good as mine. Pre-curl embracing, the only way I could get somewhat straight, non-frizzy (which is a bit generous) hair was to first blow dry completely and then use an iron. I never could figure out a way to get it even semi-straight by letting it air dry. Which should have been a very large clue that my hair desperately wanted to do something else.
